About Chainlink

Chainlink is the dominant decentralised oracle network, providing off-chain data (price feeds, randomness, event data) to smart contracts across 20+ blockchains. Chainlink secures hundreds of billions in DeFi TVL through its price feeds. CCIP (Cross-Chain Interoperability Protocol) extends Chainlink's role to cross-chain messaging and token transfers.

Pyth Network

Oracle · TVL: N/A (infrastructure)

Pyth Network is a first-party oracle that sources data directly from market makers, exchanges, and trading firms. Unlike Chainlink's third-party model, Pyth publishers are the original data producers. This enables sub-second update latency, making Pyth ideal for DeFi derivatives. Pyth's pull-based model has expanded to 40+ chains.
